I installed an official app made by the apple from there https://developer.apple.com/documentation/nearbyinteraction/implementing_interactions_between_users_in_close_proximity on my IOS 15 iPhone 11 and it doesn't work. Every time when NISession try to run it turns to suspended mod with no reasons. Does anyone have idea?

Now'sample can connected with one Third-Party Accessory to receive periodic measurements of its distance,I want to connect four accessories（not iPhone） to receive their distance and direction at the same time ,How to do that. please tell me if you know how to do that，thank you very much！

HELLO 😊 I want to range two iphones 11 to single of DWM3000EVB device at the same time (simultaneous ranging /measuring distance )via UWB nearby interaction framework will i be able to do it ? how to do it ? please let me know the code example on the side of iphone11 (swift code ) and the code on the side of DWM3000EVB how many maximum of iphones 11 are able to range / interact to one of DWM3000EVB simultaneously with UWB ranging in order to get distance ? the series or model of u1-equipped iphone is the factor of amount of iphones when UWB ranging ? for example iphone11 range to one DWM3000EVB or iphone 12 range to one DWM3000EVB or iphone 13 range to one DWM3000EVB or iphone 11 /12 /13 , 3 different series 's iphones range to one DWM3000EVB in the same event simultaneously , please let me know Thank you very much！ please see the picture below

When I checked the NearbyInteraction Accessory Protocol Specification, the sequence diagram in Section 2.4 stated (1) Establish a data link (ieBLE, LAN, Cloud, or other). However, in the sample code, there is no communication method setting for establishing the data link. Since it is described in the specification, it means that there is an arbitrary establishment method but the implementation method has not been released yet, or it is necessary to contact Apple at the time of product development and request disclosure of the specification. Please tell me who knows.

After upgrade to macOS Monterey and Xcode 13.1 my C++ projects are failing to compile. There are a lot of errors for not defined entities in various headers and a lot of linker errors for header files not found. This situation appeared after the upgrade with absolutely no changes in the codebase of my projects. Before the upgrade everything was fine and now I have more than 20 errors in one of my projects! I'm using VS Code as an IDE. Please give me advice, how to fix this issue?

By referencing to the Developer Forums, we could handle multiple concurrent sessions using iphone11. The maximum number of concurrent sessions is two. When we try to connect another one devices, session(_:didInvalidateWith:) on the NISessionDelegate is called with NIError.Code.activeSessionsLimitExceeded. I'd like to know three or more concurrent sessions are running using newer version like iphone12. Does anyone have any knowledge?
